摘要：

This report describes a reversible colourimetric and on-off-on module of fluorescent chemosensor for selective cascade recognition of Cu2+ and with unique output optical response in aqueous solution. On the other hand, F-, Cl-, Br-, I-, CH3COO-, HSO4-, ClO4-, CN- and SCN- did not induce significant changes in fluorescence. Moreover, the colour change in chemosensor LH by response of this colourimetric chemosensor can be visualised by naked eye. These fluctuations in spectral response, under electronic behaviour, can be viewed to mimic as IMPLICATION logic gate.
